Technology and R&D

Scientists in Germany have developed a new process for deposition of silicon dioxide layers during cell production. Without the need for high pressure, flammable gases, or vacuum conditions, the process could lead to cost reductions for cell manufacturers, provided it can be developed and applied in a large-scale production setting.

Spanish mounting system provider Alusín Solar has developed a solution to enable the transit of installers on roofs. It has recently commissioned a production line for this product, which it dubbed Carex.

Backsheet failures have plagued the industry, causing hefty financial burdens to many asset owners. DuPont has launched a product it says allows for easy repair of modules.

A U.S. scientist has developed a computational framework that assesses how well a hypothetical agrivoltaic project would perform in achieving desired outcomes such as the volume of PV electricity produced, and energy-to-agriculture. The method considers the high-frequency decomposition of solar irradiance into multiple rays and analyzes how these rays are propagated forward in time, to assess multiple reflections and absorption for various system configurations. It also takes into account panel inclination, panel refractive indices, sizes, shapes, heights, and albedo.

Australian technology company RayGen Resources has received funding to build a 3 MW/50 MWh ‘solar hydro’ power plant. Described by ARENA as the “first of a kind,” it is being lauded as one of the largest and lowest cost storage projects undertaken in the country. Energy giant AGL has also come onboard and will assess whether the technology would be suitable for its soon-to-retire Liddell facility.

Commodity trader Trafigura and Oslo-based ammonia leader Yara International ASA have signed a Memorandum of Understanding that will see supply of clean ammonia as well as joint R&D projects as the two companies look to promote clean ammonia as a shipping fuel and develop its value chain and infrastructure.

NASA scientists have partially cleaned up the solar modules of the Insight lander operating on Mars, by using grain sands collected nearby and trickling them on the panels during the windiest time of the day. This handmade technique has made it possible, according to them, to increase the PV array’s yield of about 30 watt-hours of energy per ‘sol,’ or Martian day.

A review of existing research on any particular topic “should provide some novel insights”, says UNSW solar researcher Dr Matthew Wright. UNSW’s new paper shows defect engineering of SHJ solar cells has come a long way, but what if these proven efficiency gains could be better applied?

Dubbed Gismo Power, the appliance is entirely mobile, can be grid-connected, and may be folded for storage.

An international team of scientists fabricated perovskite solar cells which retained almost all of their initial 21% efficiency after 1,000 hours under continuous operation at their maximum power point. The researchers credit this performance to their discovery of an additive that served to ‘block’ ions that cause device degradation, and also hope their work will contribute to an improved understanding of the relationship between efficiency and stability in perovskite PV.
